Next, we will look at the lines in detail, each with typical examples so you can see yourself in them.

CB Classic-Line – the compact round kiln for getting started and small workshops

 

For many potters, the CB Classic-Line is their first kiln of their own. It is round, compact and in many models can be run on 230 V. That makes CB especially attractive for anyone starting out with ceramics in a hobby room, basement or rental apartment who does not want to have three-phase power installed.

In practice it looks like this: you throw or handbuild bowls, mugs, small vases and figures, put them in the kiln, run a bisque firing and then a glaze firing – done. As long as you work at this scale and frequency, a CB kiln delivers reliably good results.

The round shape has two sides: it is space-saving and intuitive, but wastes some shelf space. As soon as you start firing wider plates, longer platters or larger production runs, you will notice that you are playing a lot of “Tetris” to fit everything in.

If you see yourself in one of these pictures, CB is usually a good choice:

• You fire once or twice a week.
• Your pieces are more compact than sprawling.
• You want to start solid without jumping straight into the professional class.
• You do not have a 400 V setup and do not want to have the electrics modified.

The technical basis – ceramic-fiber-free lining, protected heating elements in grooved bricks and proven TC controllers – means CB kilns quietly do their job for years in many workshops.

CBN Classic-Line – rectangular top-loading kilns for when you finally need shelf space

As soon as the first plates, platters or wider bowls are on the list, the round shape of a kiln shows its limits. You turn, shift, tilt – and still feel like you are wasting space. This is exactly where the CBN Classic-Line comes in: rectangular firing chambers that follow the logic of your work.

In everyday use, a CBN feels much “bigger” than its capacity in liters suggests. You can set kiln posts in clear rows, make clean use of kiln shelves and pack production runs so that you do not have to reinvent the layout with every firing. Anyone who has once built up several layers of plates cleanly in a CBN is reluctant to go back to a round kiln.

Typical situations in which CBN takes a lot of stress out of your firing routine:

• You regularly make plates, serving platters or large sets of mugs.
• You use kiln furniture kits with several levels and want to load them in a structured way.
• You find that your round kiln is “full” even though it feels like there should still be room.

That makes CBN one of the most sensible lines for anyone who works seriously but wants to stay with a top-loading kiln. The rectangular chamber brings order, efficiency and calm to loading – without the jump to the front-loading price class.

SQ Squadro – square firing chambers for even glaze firings

The SQ Squadro line is something of an insider tip in the KITTEC range. Square firing chambers are a very good answer to the question of how to bring uniformity, use of space and outer dimensions into a balanced relationship. Neither round nor extremely rectangular – just a compact, easy-to-load interior.

You see SQ kilns in many schools, course workshops and studios because they deliver a reliable, even firing result – regardless of who is firing. Glaze tones repeat, edges run out cleanly, and there are fewer surprises between the top and bottom levels.

SQ is a particularly good fit if:

• you run glaze firings frequently and value even results,
• you want a well-usable floor area despite limited space,
• several people work with the kiln in your setting (classes, shared workshop).

While CBN delivers maximum shelf space, SQ is the line that offers a very balanced mix of uniformity, usable area and compactness. If you glaze a lot and want a “well-behaved” firing character, SQ is often the right choice.

CT Classic-Line – front-loading kilns for when ceramics is part of your working life

The step from a top-loading to a front-loading kiln is less an upgrade than a change of category. With a CT kiln you change your entire workflow: you load at eye level, can set shelf levels exactly, place heavy pieces without contortions and get a completely different level of control over the interior.

CT kilns are built for continuous use in studios, workshops and educational institutions. The three-layer, ceramic-fiber-free insulation, the mortar-free brick lining and the robust door mechanism are designed for long service lives. The firing results are clearly more uniform than in many top-loading kilns – especially in the larger volumes.

There are two important variants within the CT line:

• CT-3: Heating via the sides and back wall. Very good uniformity for bisque and glaze firing, ideal for mixed use with many standard tasks.
• CT-5: Heating via the sides, back wall, floor and door. Maximum evenness throughout the firing chamber, especially interesting for demanding glazes, thicker pieces and users who need highly reproducible results.

If you fire regularly, teach classes, sell your work or work with more complex glazes, CT is the line from which a kiln no longer feels like “a machine” but like a reliable production base.

X Professional-Line – when maximum uniformity is the top priority

The X Professional-Line is intended for users who push glaze firing to the limit of what is reproducible and controllable. Construction, mass and heating are designed even more consistently for stability and evenness here than with CT.

X kilns are often found where:

• firing happens every day,
• high piece counts or large objects are involved,
• glazes are developed or reproduced at a high level,
• training takes place at a professional standard (art academies, vocational schools).

If glaze firing quality, reproducibility and continuous operation are central concerns for you, X is the most uncompromising line in KITTEC's electric range.

CBR Classic-Line – gas, raku and lively surfaces

Electric kilns are ideal for controlled, oxidizing firings. For raku, reduction firing and deliberately “lively” surfaces, though, you need gas. The CBR Classic-Line is made exactly for that: thermal shock resistant lining, robust burner technology and an open design that allows rapid temperature changes.

Typical uses include:

• outdoor raku workshops,
• reduction firings with deliberate flame control,
• experimental surfaces and specialty glazes.

CBR complements electric lines such as CB, CBN, SQ, CT or X; it does not replace them. Many studios have an electric kiln for bisque and glaze firings and a CBR in addition for raku and experiments.

CBG – Gas Front-Loading Kiln for Large Formats and Ambitious Studios

CBG is the gas answer to large ceramic projects: front loader, large firing chambers, multiple burners and a stable, solid construction. This line is used where large sculptures, installations or series are to be fired under gas conditions, often in training facilities, large studios or specialized workshops.

If gas firing is a central part of your artistic language and you want to fire large work rather than just small raku pieces, CBG is the logical choice.

Conclusion: The Line Determines Your Daily Routine, the Model Only the Size

KITTEC does not simply offer “lots of kiln models”, but clearly defined lines developed for different ways of working. The key insight: once you have found the right line, choosing the model is only a question of volume.

Round CB kilns are perfect for getting started and for small spaces. Rectangular CBN top-loading kilns bring order and floor space efficiency to your firing routine. SQ delivers square firing chambers with high homogeneity. CT front-loading kilns bring you into the professional, ergonomic world of firing. X is built for the highest demands on reproducibility. CBR and CBG, finally, open the door to the world of gas and raku.

If you are unsure which line best suits your work, your space and your budget, a short, honest consultation is worth it. Simply describe how you currently fire, which pieces you make and how you want your studio to develop over the next few years, and together we can narrow down which KITTEC line will take your ceramics to the next level.
